People can learn to control a robotic third arm using their eyes and chest muscles. Such extra limbs could become essential tools for surgeons or people working in industrial jobs, say researchers.

Researchers at the University of California, San Francisco, have enabled a paralysed man to regularly control a robotic arm using signals from his brain, transmitted via a computer.

Renard, in addition to his work as an instructor, is a software engineer and has built a robotic arm using Arduino and Raspberry Pi, among other technologies, experience he uses in his teaching.

But what if there was a way to bridge that gap? This robot arm guide offers a guide to building a mini robotic arm using Arduino, complete with 3D-printed parts and easy-to-follow instructions.
